Slippery Elm (Ulmus rubra) is a tree native to North America that can grow over sixty feet in height. It possesses a rich red heartwood that most likely gave it its common name "Red Elm" and it can also be found under the names of Gray Helm, Soft Elm, Moose Elm and Indian Elm, and is perhaps most closely related to the European Wych Elm. Its fibrous bark has made it popular for a variety of uses ranging from the creation of twine, rope, thread, and even bows strings. The wood is also popular in making sturdy wood structures, and was popular for wagon wheels due to its interlocking grain which can better absorb shocks.

In modern usage its bark has become popular as a powder which is then often used as a tea. The tea is said to be good herbal remedy for soothing the digestive tract, and is even considered by some to be a useful treatment for easing Crohn's Disease and Ulcerative Colitis. It has also been used to treat diarrhea, cough, and sore throat, and is sometimes used externally for wounds and burns.
